Embodiment Construction

Referring to FIG. 1, a computer system 10 is illustrated which comprises a system unit 12 that receives manual control inputs from an attached keyboard unit 14 and displays system responses on a display screen 16 of a display device 18. The keyboard unit 14 includes a surrounding rectangular frame 20 that supports a plurality of manually depressible keys 22. The keys 22 include the normal twenty-six keys bearing the letters of the alphabet which are arranged in the conventional QWERTY layout. The keys 22 also include conventional F1 through F12 function keys, and other keys such as CAPS LOCK, SHIFT, TAB, BACKSPACE, ENTER and so forth. The keyboard unit 14 further includes a SPACE BAR key 24 a CTRL key 26, and ALT key 28, another ALT key 30 and another CTRL key 32 (not shown).

The keyboard unit 14 (FIG. 1) has a small, substantially rigid joystick actuator 34 embedded therein between the G, H and B keys. The joystick actuator 34 can be engaged by the tip of the user's index finger and...

Abstract

An integrated manual control input device is provided for use in a computer system having a graphical user interface. The device comprises a pointing actuator mounted to a computer keyboard between preselected ones of the keys for engagement by a user's index finger. The pointing actuator includes a coil in the form of a cylinder that, when carrying a current, produces a magnetic field to drive a ferromagnetic slug to provide tactile feedback to a user of the control input device.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates generally to computer systems with graphical user interfaces and, more particularly, to control of computer activities with graphical user interface pointing devices.2. Description of the Related ArtThe interactive computer system operating environment, such as encountered by users of personal computers and the like, is characterized by efforts toward increasing ease of operation and convenience. An important contribution to making the operation of such computers easier and more convenient is the graphical user interface (GUI). A GUI provides a computer interface that is visually oriented and includes a variety of graphical artifacts displayed on a computer display that make the operation of the computer more intuitive and thereby can increase user efficiency.A GUI operating system enables a user to move a computer display pointer by using a GUI pointing device such as a display mouse or track ball that is at...
